AD Direct Digital Synthesis Modules. The circuit is taken directly from the example in the AD datasheet. and uses a MHz clock and a 40MHz output. Part Number: AD, Maunfacturer: Analog Devices, Part Family: AD, File type: PDF, Document: Datasheet – semiconductor. Introduction. This module described here is based on ADS, a CMOS, MHz, and Complete DDS. Synthesizer. The AD is a highly integrated device.

I am new to this forum. Hi All, I am using the AD with a pic microcontroller for outputting a square and sine wave in the range of khz.

Any idea how I can turn off the AD!!! ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. More power and Thank you. I tried it, and it really work. He looked over everything. I have it transmitting using this method so far and very impressed with this inexpensive module.

If a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact ADI. There are some very similar 1.

This is the date Analog Devices, Inc. Then it is the third pin from the right on the datasbeet row. I succeeded in getting this operating with no difficulty. The model has not been released to general production, but samples may be available. Hi, Ron Many thanks for sharing info and code for using AD along with arduino. Have you considered making this an audio sweep generator?

Using digital pins 8 through 11, proto shield installed on the UNO.

Your code is compiling and working great. The square wave will suddenly appear; its duty satasheet is very sensitive to the adjustment of the pot.

Are there differences in quality of components in different batches of modules?

Arduino – AD Waveform Generator

Just not working and need help. My eBay DDS worked fine with your sketch.

The Sample button will be displayed if a model is available for web samples. I’ve set it in software to ” -ie maximum brightness. Please Select a Language. Based on this site I built a programmable frequency generator using an arduino to control the DDS. Pretty impressive little board. I found more data online, and the seller could not provide support. Good luck with your project. Also, please note the warehouse location for the product ordered. ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability.

Therefore, I’ve limited the available frequency range from 10 Hz to 10 MHz in the software. The square wave’s duty cycle is adjusted with a pre-set potentiometer on the module itself. I think it would be neat to use the with a LCD keypad shield and be able to just cursor over to the digit you want to change, hit up or down, and then select.

Testing an eBay AD9850 DDS module with Arduino Uno

This is just above the audio range so you can use almost any audio amplifier schematic maybe with some modifications. Hi Ron, Thanks for the sketch, I have had my arduino ages, but lack the gumption to get stuck in to it. May you can explain the way, how to calculate the frequency on the output on my AD
